Abstract
Results of Raman measurements on R(Formula presented)(Formula presented)C (R=Lu, Ho, Y) single crystals are reported. Raman peaks are observed at 190 (Formula presented) and near 830 (Formula presented). From the polarization-dependence measurements, these peaks are assigned to be the Ni-(Formula presented) and the B-(Formula presented) modes, respectively. Raman study on the effects of boron isotope (Formula presented) substitution for (Formula presented) in the (Formula presented)(Formula presented)C crystals confirms that the mode near 830 (Formula presented) is due to the vibration of B atoms. However, from these single crystals, the expected Ni-(Formula presented) and B-(Formula presented) modes are not observed.
